You're right. I'd kick myself but I tore my groin muscle playing softball 
over the weekend and that would be just too painful to attempt. ;-P

Since I have your attention (although you might be already out of the 
office) I'm dying on another script - but this time trying to get it 
working in IE (it works in Netscape fine.)

I stole some code from a script I used for form validation, which works 
fine in both browsers (it's currently in production use.)

Here part of the code I borrowed:

...

var requiredFields = new Array("FirstName","LastName",
"Password","Verify","Address1","EmailAddress","City",
"DaytimePhone","StateOrProvince","Country","PostalCode","Username");

var fieldNames = new Array("First Name","Last Name",
"Password","Verify Password","Street Address",
"Email Address","City","Day Time Phone","State",
"Country","Postal Code","User Name");

...

for(var fieldNum=0; fieldNum < (requiredFields.length); fieldNum++) {
  if ((input.elements[requiredFields[fieldNum]].value == "") ||
     (input.elements[requiredFields[fieldNum]].value == " ") ||
     (input.elements[requiredFields[fieldNum]].value == "NotSelected"))
  {
   fieldsNeeded += fieldNames[fieldNum] + "\n\t";
   fieldCheck = false;
  }
}

...etc...


This is what I transmografied it into:

var varDirection = true;
function PreSelectMajors(input) {
     var majorsIDs = new Array('201','208','501');
     var varCheck = true;

     if (varCheck) {
         for(var fieldNum=0; fieldNum < majorsIDs.length; fieldNum++) {
             input.elements[majorsIDs[fieldNum]].checked = varDirection;
         }
         if (varDirection) {
             varDirection = false;
         } else {
             varDirection = true;
         }
     }
}

Note: The majorsIDs array is created on the fly by ASP. Also if the array 
is "blank", the ASP script will set varCheck to false, so the function 
doesn't really do anything.

OK - This runs great with Netscape. IE throws an error on the line:

     input.elements[majorsIDs[fieldNum]].checked = varDirection;

It says:

         Error: 'elements[...]' is not an object.

What gives? I'd kick my machine out the window except my leg hurts too much.
